thatthe ditional detent or. retainer D, in the'shap'e the shaft 3 aiidcarry the retaining blade away from the hammers.

Each detent C is connected with a. spring k,'which tends to carry thehoqk'of the detent into engagement with that of the hammer; and it willbe evident that where the detents are operated from the carriers A,

- "the-hooks or the detents would'again, be brought mto engagement' withthose of the 10 hammers after the carriers moved away from the rollersG, unless the tails ofthe carriers beyond the shoulders a were undulyrolonged. To avoid the necessity of thus engthenm these tails I providemeans whereby a er the detent'sare swung away from the'ha'mmers theycannot, return until the-printing operation is affected and thepartsrestoredto position. For this purpose.

provide each hammer with two bearings or shoulders 'w, g ,'the retainingblade being normally upon the shoulder y, but being the-roller G, sothat'thehammer is per- .mittedto swing to a limited extent, but;

- sufiicientto-car its hook to such a height I thatthe hook o the detentC cannot again flengagethe-s'amea when the carrier passesof the retainerfrom: the shoulder w,- releasfrom theroller G, the subsequent movementing the hammer.

} at the right of the'figureswhichare printed in an item (the-termfigure as herein emplo'yednotincluding the"cipher) I make," use ofoverlappin tails 2, uponthe de- :tents C, so that -w en the detent isswung insuch case being norma to release its associated hammer the tailof the. said-detent willact upon the next detent at the-right, and thisupon the next, and so on, to move all of. the detents at the ri ht ofthe one first adjusted to release of the hammers at the rilgh't, thecarriers y set to bring the, cipher type in position-to print, or, as

- eration of the machine.

To.

this end the overlapping tails z 0 not extend from one retainer tothevother, but simply extend far enough to make contact with anadjustable bearing J frictionally secured upon the next detent, saidbearin bei'ng'shown in the form of a lever pivote to the detent in suchposition that it may be swungiout of position andwhen so'swun willafl'ordno contact point for the tail 0 the adjacent detent an nomovement will therefore be imparted from one to the other.

It will be evident that an equivalent-for the shoulders 'v, w on thehammers would be shoulders on the retainer to allow a preliminaryshort-:movement of the hammers before releasing them. see Fig. 3."Without limiting-myself to the construction and arrangement shown, Iclaim:
